Traditionally, research works related to quality in telecommunication services have consisted of a series of analysis over a set of critical-to-quality technical parameters and a resulting enhancement proposal. However, in this Phd. Thesis we aim to face the quality issue from an overall point of view: Not only analysing the objective performance of those agents involved in service provision but also by trying to assess which is their effect in final users’ satisfaction, since this must be the final goal of this kind of systems.
We have carried out a State of The Art focused on four different areas: technical QoS, subjective quality assessment models, corporative quality management systems and integrating approaches. Based on this work we have identified several deficiencies that will determine the characteristics that the model should show. Among these deficiencies pointed out, the lack of a methodological and quantitative analysis of the real impact of the technical performance over users’ satisfaction stands up above all.
There is a clear need for a model that allows to represent different quality aspects with an integrating approach. This new model should provide different user profiles (both technical and non technical ones, providers, end-users and regulation agencies) with useful information.
Our proposal comprises both a theoretical model and an application methodology that eases up its use by other researchers.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
